The Hall effect is due to the nature of the current in a conductor. Current consists of the movement of many small charge carriers, typically electrons, holes, ions (see Electromigration) or all three. When a magnetic field is present, these charges experience a force, called the Lorentz force. When such a magnetic field is absent, the charges follow approximately straight paths between collisions with impurities, phonons, etc. However, when a magnetic field with a perpendicular co… WebA Hall effect sensor (or simply Hall sensor) is a type of sensor which detects the presence and magnitude of a magnetic field using the Hall effect.The output voltage of a Hall sensor is directly proportional to the … hage hodes attorneys at lawWebThe Hall effect is used today as a research tool to probe the movement of charges, their drift velocities and densities, and so on, in materials.
